Crouse-Hinds CB3HDG – Frequently Asked Questions

1) What trade sizes does the Crouse-Hinds CB clamp back spacer come in?
Five trade sizes cover the range: 3/4 inch (CB2HDG), 1 inch (CB3HDG), 1-1/4 inch (CB4HDG), 1-1/2 inch (CB5HDG) and 2 inch (CB6). Match the spacer to the conduit trade size you are running, not to the strap bolt. Note the 2 inch is ordered as CB6; the smaller four carry the HDG hot-dip galvanized suffix.
2) Can I use these clamp back spacers outdoors or in a wash-down area?
Yes. The CB2HDG through CB5HDG spacers are hot-dip galvanized malleable iron, which is the finish specified for exposed and outdoor conduit, including sustained weather exposure. For corrosive interiors or coastal exposure that finish is also the right call over plain or electro-plated hardware.
3) Does the clamp back spacer come with the conduit strap and mounting bolt?
No. The Crouse-Hinds CB is the spacer only, the back piece that lifts the run off the surface. You order the one-hole or two-hole conduit strap and the anchor or bolt for your substrate separately, sized to the same conduit trade size as the spacer.
4) What does a clamp back spacer actually do on a conduit run?
It sits between the conduit strap and the mounting surface so the pipe stands off the wall instead of laying flat against it. That gap gives you airflow behind the run, keeps moisture from being trapped against the conduit, and leaves room to get a wrench or an inspector's eye on the run later. On the Crouse-Hinds CB spacers the body is malleable iron, so it carries the load of a rigid run without flexing.
5) Is a clamp back spacer the same thing as a parallel groove or tap clamp?
No, and they are not interchangeable. A clamp back spacer like the Crouse-Hinds CB is raceway support hardware, it just stands conduit off a surface. A parallel groove clamp such as the Burndy UC25R2RS Tapit is a conductor connector, used to tap or splice cable. If you are supporting pipe you want the CB; if you are making a connection on a conductor you want the Tapit.
6) Can a Burndy UC25R2RS Tapit clamp be used in place of a Crouse-Hinds CB3HDG clamp back spacer?
No - the two are different kinds of hardware despite both being called clamps. The Crouse-Hinds CB3HDG is a 1-inch clamp back spacer in malleable iron with a hot-dip galvanized finish, used to hold a conduit run off the mounting surface so the raceway is spaced away from the wall or structure. The Burndy UC25R2RS is a Tapit parallel groove clamp in aluminum alloy, which is a conductor connector for joining or tapping wire, not a conduit support. If you are strapping conduit, stay with the CB-series spacer in the trade size that matches your conduit - 3/4 inch, 1 inch, 1-1/4 inch, 1-1/2 inch or 2 inch.
7) I need to standardize conduit support hardware across a plant. Can I spec one family across sizes?
Yes. The Crouse-Hinds CB clamp backs run from 3/4 inch through 2 inch in the same malleable iron, hot-dip galvanized construction, so a facility can carry one family across its rigid conduit sizes and keep a single finish spec for indoor and exposed runs. Stock CB2HDG, CB3HDG, CB4HDG, CB5HDG and CB6 to cover the range.
